Abstract

本实用新型提供一种风电主轴法兰盘初锻工装,包括锻模和锥面镦粗板,锥面镦粗板的锻压工作面呈向下凸起的去顶的圆锥面。锥面镦粗板的锻压工作面呈向下凸起的去顶的圆锥面,在风电主轴法兰盘初锻过程中,通过对锥面镦粗板施加压力,使锻件在该种锥面镦粗板工作面的作用下,被向外挤压,而不是像现有平面镦粗板工作面仅给锻件垂直下压力还有很大的摩擦力,使得风电主轴法兰盘初锻时间减少,提高了风电主轴法兰盘初锻效率。在初锻后,采用具有平工作面的上砧子继续镦粗模锻,最终完成风电主轴法兰盘模锻。

The utility model provides a preliminary forging tool for a flange of a wind power main shaft, which comprises a forging die and a conical upsetting plate. The forging working surface of the conical upsetting plate is a conical surface that protrudes downward and removes the top. During the initial forging process of the wind power spindle flange, by applying pressure to the conical upsetting plate, the forging is upsetting on the conical surface. Under the action of the working surface of the rough plate, it is extruded outward, instead of only exerting vertical downward pressure on the forging and having a large friction force like the existing flat upsetting plate working surface, which reduces the initial forging time of the wind power spindle flange. The initial forging efficiency of the flange of the wind power main shaft is improved. After the initial forging, the upper anvil with a flat working surface is used to continue the upsetting die forging, and finally complete the die forging of the wind power main shaft flange.

风力发电是国家大力提倡的清洁能源发电,在我国正不断发展,主轴是风力发电设备的一个组件,随着风力能源的不断开发,主轴需求量也随之增加,如何在保证产品质量的情况下提高效率是目前锻造行业竞争的核心。因法兰盘薄,直径大,且轴身细,台阶差大,采用自由锻费时又费力。图1示出了现有的一种风电主轴法兰盘模锻工装,包括锻模2和上砧子1,上砧子的锻压工作面是平面,在风电主轴法兰盘镦粗锻造过程中,始终采用这种平工作面的上砧子对锻件进行锻压,耗时长,锻造效率低。 Wind power generation is a clean energy power generation strongly advocated by the country. It is developing continuously in our country. The main shaft is a component of wind power generation equipment. With the continuous development of wind energy, the demand for main shafts will also increase. How to ensure product quality? Improving efficiency is at the heart of competition in the forging industry today. Because the flange is thin, the diameter is large, the shaft body is thin, and the step difference is large, free forging is time-consuming and laborious. Fig. 1 shows an existing wind power main shaft flange die forging tool, including forging die 2 and upper anvil 1, the forging working surface of the upper anvil is plane, during the upsetting forging process of wind power main shaft flange , Always use the upper anvil with this flat working surface to forge the forging, which takes a long time and the forging efficiency is low.
